Saf ety Precautions Refer to on page .
We recommend that you use premium unleaded fuel because it produces
fewer engine deposits and extends the life of exhaust system
components.
Use of lower octane gasoline can cause persistent ‘‘pinging’’ or ‘‘spark
knock’’ (a loud rapping noise) which, if severe, can lead to engine
damage. Light pinging experienced while operating under a heavy load,
such as climbing a hill, is no cause for concern.
If pinging or spark knock occurs at a steady engine speed under normal
load, change brands of gasoline. If pinging or spark knock persists,
consult your Honda dealer.
Never use stale or contaminated gasoline or an oil/gasoline mixture.
Avoid getting dirt, dust, or water in the fuel tank.
Your engine is designed to use any premium gasoline that has a pump
octane number of 91 or higher. Gasoline pumps at service stations
normally display the pump octane number. For information on the use
of oxygenated fuels, see page
